摘要
利用中国学术文献网络出版总库及万方数据知识服务平台,选取有关慕课研究文献的高频关键词,两两组配并统计其在同一篇文献中的共现次数,构造共词矩阵,进而转化为相关矩阵、相异矩阵,对相异矩阵进行多维尺度分析,探讨我国慕课在教学改革、开放教育、信息技术发展、资源建设、图书馆服务创新等方面的研究热点及慕课的发展趋势。
High frequency key words in papers on MOOC were retrieved from CNKI and Wanfang Data Knowledge Service Platform.A co-words matrix was constructed , which was then transformed into correlation matrix and dis-similarity matrix, respectively.The correlation matrix was analyzed by multidimensional scaling analysis to show the hotspots in domestic MOOC studies on teaching reform, open education, information technology, resource develop-ment, library service innovation and its development trends.
